A Fire Inside is an EP by American rock band AFI. It was released on September 29, 1998 through Adeline Records. The EP title is a quote from the introductory track on their previous album Shut Your Mouth and Open Your Eyes, as well as the band name's permanent abbreviation. The EP includes two original songs and two covers. Although the EP is out of print and no longer sold in current retail stores, it can be found on iTunes for digital download. In November 2010, Adeline Records released a special edition pressing on purple vinyl, limited to 500 copies.
It is the first release to mention Hunter Burgan as a permanent member, and the last to feature guitarist Mark Stopholese.
